16 Bit Home Computer Graphics Archive
Werner Randelshofer has set up an ample collection of computer graphic animations from the 80’s and 90’s, both commercial and home-grown. Examples come from works demonstrated on the Commodore Amiga, the Atari ST and the PC.
The examples above are only a taster of what has been documented - there is plenty of 2D stills and animation, but also early experimentation with 3D. Plenty of what you see is work before the GIF file format or Flash were invented.
